The edition of the correspondence of Johannes Hevelius is an enterprize conducted in partnership by the International Academy of the History of Science and the Polish Academy of Sciences, under the auspices of the International Union of Academies, with the support of the Juanelo Turriano Foundation.

The first volume, the Critical Prolegomena, under the direction of Chantal Grell, came from the printers on 4 April 2014 and was presented to the mayor of the city of Gdansk and the Polish authorities on 7 April 2014. It contains a new biography of Hevelius (Chantal Grell), a short overview of the constitution of the Hevelian corpus (Harald Siebert), a description of existing manuscripts and a history of their dismemberment by Libri (Susan Keyes), a very precious chronological inventory of the letters (Susan Keyes, Klaus-Dieter Herbst), subsidia heveliana, an overview of the historiography on Hevelius (Chantal Grell, Klaus-Dieter Herbst, Maria Otto, Maciej Jasinski).
The Critical Prolegomena will be presented to the scientific community in the fall at the Paris headquarters of the Polish Academy of Sciences.

Correspondence published in the paper volumes will be simultaneously published online in the Brepols Library of Latin Texts (LLT).

The ultimate goal is to produce an electronic edition in chronological order.
